SHOCK-ABSORBER.

Application filed March 13, 1916.

T 0 all whom it may concern:

Be it known that I, RAY HYNE, a citizen of. the United States, residingat Evansville, in the county of Rock and State of VVisconsin, haveinvented certain new and useful Improvements in Shock-Absorbers; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention which relates to improvements in shock absorbers, has forits object to provide adevice of this class which may be simply andinexpensively manufactured and marketed, yet which when in use will behighly efficient and durable.

lVith this general object in view, the invention resides in certainnovel features of construction to be hereinafter fully described andclaimed, the descriptive matter being supplemented by the accompanyingdrawings which constitute a part of this application, and in whichFigure l is a side elevation partly in section showing the inventionapplied, and Fig. 2 is a perspective view of a part of the axle engagingclamp and the bar by which the shock absorber proper is secured to saidclamp.

In specifically describing the construction shown in the drawing abovebriefly described, similar reference characters will be placed oncorresponding parts in both views and reference will be herein made tothe numerous elements by their respective indices. To this end, thenumeral 1 designates a cylinder preferably constructed of a singlelength of brass tubing of proper diameter, the upper and lower ends ofsaid cylinder being closed by upper and lower caps 2 and 3 shown in thepresent embodiment of the invention as threaded on said cylinder. Bothcaps '12 and 3 are formed with central external enlargements 4 for thereception of a wrench in applying or removing said caps, and in additionto these enlargements, bosses 5 are formed integrally with said caps,said bosses extending from the peripheries of the latter to theaforesaid enlargements & as shown and being adapted for securing thecylinder to a clamp yet to be described. The enlargeniei'it -L of theupper cap 2 cooperates with a gland 6 in forming a stuffing box throughwhich an upright rod 7 passes slid- Specification of Letters Patent.

ably, the lower end of said rod carrying a circular plunger plate 8preferably out of contact with the cylinder 1 and having perforations 9through which oil or the like confined in said cylinder may pass slowlyto allow the rod 7 to move gradually into and out of said cylinder, itbeing understood thatsaid rod is secured to the body of the vehicle,whereas the cylinder is fixed to one axle thereof. For attaching theupper end of the rod 7 to the body of the vehicle, the depressed centralportion 10 of a strap of metal 11 is threaded on the upper end of saidrod and locked thereon by a nut 12 disposed in the depression of saidstrap, the ends of the latter having apertures through which attachingbolts or the like 13 are passed.

Secured by a machine screw or an equivalent device ll to the boss 5 ofthe upper cap 2, is the upper end of an upright bar 15, the lower end ofsaid bar being bent upon'itself as shown at 16, extended upwardly to apoint substantially midway between the bosses 5 and being here directedoutwardly as shown at 17, thence upwardly at 18, being then bent againupon itself as disclosed at 19 and tern'iinating in the form of aC-shaped clamp member 20 having a depending car 21. A second screw orthe like 22 passes through the bar 15 directly above the bend l6 andinto the boss 5 of the cap 3. This manner of constructing the member 20and securing it to the cylinder will positively prevent removal orloosening of either of the caps 2 and 3, as well as being a simple andinexpensive yet rigid and durable formation. As shown clearly in Fig. 1,a second C- shaped clamp member-23 cooperates with the member 20 tosecure the device on the axle of the vehicle, bolts 2- being providedfor drawing the two members together.

"hen manufacturing the improved shock absorber, or after the same isapplied, the cylinder 1 will be filled with oil or another suitablefluid, whereby the plunger plate 9 is retarded in its inward or outwardmovement, thus absorbing violent jars which would otherwise betransferred directly from the wheels of the vehicle to the body thereof.The improved device will also effectively prevent the undesirableresults often caused by the recoil of the vehicle springs. In short, itwill be found to be not only a simple and inexpensive article,

but one which will be highly efficient and durable and will possess anumber of advantageous characteristics.

I claim:

1. A shock absorber including an upright cylinder to contain shockabsorbing means, said cylinder having upper and lower detachable capsclosing its ends, an upright bar rigidly secured at its ends to saidcaps to prevent removal thereof, and a clamp secured to said bar forattaching the cylinder to the running gear of a vehicle.

A shock absorber including an upright cylinder to contain shockabsorbing means, and an upright bar rigidly secured to the ends of saidcylinder, said bar having one of its ends bent backwardly and formedinto a Clamp member to assist in securing the cylinder to the runninggear of a vehicle.

3. A shock absorber including an upright cylinder to contain shockabsorbing means, an upright bar rigidly secured to the ends of saidcylinder, one end of said bar being bent upon itself and directedoutwardly, said end being then again bent upon itself and further bentinto sul'istantially the form of a- C to constitute a clamp member, andan additional clamp member (-oiiperating with the aforesaid member tosecure the cylinder to the running gear of a vehicle.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
